AC issue on my ISX

^^^ Thats Correct ^^^

Contrary to what the general public thinks, more freon than the systems call for will NOT make A/C colder...in fact, it's just the opposite. However, they will absolutely freeze up with a certain amount lower than what is called for.

- David24, you need to check your hi/low pressures and see where they are in relation to the outside ambient temp. A variety of issues can cause what you're describing, but you need to start with some manifold gauges to monitor system performance. Somone who knows how to read the gauges properly can usually hit the nail on the head in just a few minutes.

**Again, more freon is usually a bandaid and rarely the correct answer to your issue so beware of someone wanting to stuff more into your system without proper diagnosis.
